The present invention relates to a dual-targeting antibody targeting stem cell factor (SCF) and galectin-1 and a composition for preventing or treating angiogenesis-related diseases comprising the same. The present invention provides a dual-targeting antibody derived from a human monoclonal antibody which may effectively inhibit angiogenesis by simultaneously neutralizing SCF and galectin-1 involved in angiogenesis, and a pharmaceutical composition for preventing or treating angiogenesis-related diseases comprising the antibody. The dual-targeting antibody according to the present invention may effectively prevent or treat angiogenesis-related diseases by simultaneously neutralizing two targets involved in angiogenesis wherein the angiogenesis-related diseases cause hemorrhaging by blood vessels changing due to abnormal angiogenesis and thus increasing the permeability thereof.
